Good point! Thorin is very cold towards Bilbo throughout most of the film. Then again, Thorin is a dwarf on a mission and Bilbo is a winer and does complain quite a lot. Even though he got Thorin and Co out of a few jams, he also put them in a few.

True. I hope we get to see Balin's revisit to Bag End with Gandalf in the third film. He's such a pleasant fellow. Dori seemed to be a bit too polite, I thought.
